Fellow TechNetters:

   In today's world of High Volume Production.   What is a good YIELD Rate.   Back some 30 years I remember 89 to 92% yield depending on board complexity.   Our AOIs weren't as good and accurate as todays.   I need some kind of warm and fuzzy number.   We used to put external image numbers on all boards to help sort repeat images printing anomalies.   What happened to the PERFECT COUPON that was to HELP solve these type of issues.

   I also see frequent Front to Back cores misregistration!!!!!   What's up with that anomaly.

Victor,
